I don't usually like attacking people on forums, but calling Katarina easy to play somewhat offends my ego (I'll come right and say it). She's WEAK and SQUISHY early game like none other. It takes skill to effectively harass, level, and gain enough money to be decent or carry. Dying is far too easy and devastating. Granted, once she's powered up (or if you play really weak people), she's a killing machine with Shunpo and Death Lotus, plus that W key. In the end, she's very enjoyable though, essentially able to destroy the enemy team with a well timed shunpu and death lotus.
